Your Anima will attune to you the more you use a certain Anima over time, though you can opt to use different ones. That is because they are like Dragoons, and will bond with the user. Due to Taiga's enhancements, you can unlock the Anima's old powers or insert some of your own powers to be be used through the Anima at certain points in the story depending on how you use them. Also the Angel's Mark can be used to help power the Animas.

For free form the stats of the Anima will be used versus the enemy Gear/Anima to determine the winner. Speed gets higher start order and such. Boss Battle Mode will be a fleshed out mode of this.
